Item Description

– The Linear IC Trainer Model ELTR 008 covers both the basic & advance linear electronics as follows:
– Study of operational amplifier (op-amp IC 741) parameters such as input resistance, slew rate, frequency response, input offset voltage input offset current input bias current, CMRR,
differential input resistance, unity gain band width rated output & full power response.
– Study of operational amplifier amplifications such as inverting, amplifier, non- inverting amplifier, difference amplifier, inverting, summing amplifier and voltage follower.
– Study of operational amplifier basic application such as adder, subtractor, multiplier, divider, integrator, differentiator, limiter, comparator ( level detector ) and Schmitt trigger
– Study of operational amplifier advance applications such as active LPF / HPF, zero crossing detector, AC-DC converter and waveform generators.
– Study of operation and characteristic of a Timer (IC555).
– Study the timer applications such as astable / monostable / bistable multivibrators, frequency divider, PWM, PPM, 50% duty cycle oscillator & timers.
– Study the operation of voltage regulators for positive / negative fixed and variable outputs.

– Many other experiments can be designed / performed using the onboard components and special vero-board provided (for use of external components without soldering).
